It's always too early to quit.

To know oneself, one should assert oneself.

The wise does at once what the fool does at last.

Things do not happen. Things are made to happen.

Expect problems and eat them for breakfast.

Problems are not stop signs, they are guidelines.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

If you think you can do it, you can.
